PROCESS FOR MAKING A EESILIENT FIBER.

Specification of Letters Patent.

Application filed October 10, 1907. Serial No. 396,8 41.

- a citizen of the United States, and a resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes for Making a Resilient Fiber, of which the following is a specification.

This invention relates to a process for making resilient fiber which is specially applicable to a lubricating packing, but can be used for other purposes. Its objectspecifically is the process to make a fiber which will have the requisite resilience to maintain a fibrous conductor in continuous contact with the object, like a journal that is to be lubricated. To produce the resilient fiber, a vegetable fiber, like coir fiber is treated for a out thirty 'minutesin a bath of caustic soda of about 30 Baum which produces an alkaline lignin, curling the fiber and making it resilient. The fiber is then placed in a bath of acetic acid of 1 Baum for about twenty minutes which neutralizes any excess of alkali resent. Next it is treated in a bath of an' in, composed of one part of anilin and five hundred parts of water to set the fiber, after which the said fiber is dried by heat when used for a lubricating packing.

By the terms set the fiber or setting the fiber as used in the specification and claims is meant giving fixed form to the fiber.

The prepared fiber as just described is mixed in a picker with cotton yarn and wool yarn in the followin proportions: twenty per cent. of the'coir fi er, forty five per cent. cotton yarn, and thirty five per cent. wool yarn.

In the accompanying drawing the coir fiber is shown at 10, and the cotton yarn and wool yarn at 11 and 12 respectively.

The packing may be modified by mixing the coir fiber with either cotton yarn or wool yarn, thereby omitting one of the lat- ]Patenteol May 3, 191109.

ter elements. The packing is specially applicable for journal boxes of car axles.

Having described my invention, I claim: 1. The process of making a resilient fiber consisting in treating a vegetable fiber to an ankali to make it resilient, neutralizing any excess of alkali present by an acid solution, then setting the fiber in a bath of anilin, and finally drying the product.

2. The process of making a resilient fiber consisting in treating coir fiber to an alkali to make it resilient, next neutralizing any excess of alkali present by an acid solution, then setting it in a bath of anilin and finally drying the product.

3. The process of making resilient fiber consisting in treating a vegetable fiber in a bath of caustic soda to make it resilient, next neutralizing any excess of alkali present in a solution of acetic acid, then setting the fiber in a bath of anilin and finally drying the product. V

4. The process of making a resilient fiber for lubricating packing consistin in treating coir fiber in a bath of caustic soda to make the fiber resilient neutralizing any excess of alkali present 1n 2. bath of acetic acid, then setting the fiber in a bath of anilin and finally drying the-product.

Signed at the borough of Manhattan in the county of New York, and State of New York, this 8th day of October A. D. 1907.
